Topik kedua pada hari ini adalah mengenai mutual redistribution yang artinya apabila terjadi saling redistribusi antar routing protocol.
Untuk lab kali ini, routing protocol yang digunakan adalah OSPF dan RIP.
Mutual redistribution bila hanya satu titik tidak memiliki resiko apapun, namun apabila terjadi pada 2 titik, akan rentan terjadi routing loop.
Lab 2 - Mutual Redistribution - 2 titik
Topologi yang digunakan pada lab kali ini adalah sbb :
Routing OSPF : R1, R2 dan R3 pada area 0
Routing RIP : R2, R3 dan R4 menggunakan RIPv2
Konfigurasi router R1 :

Untuk router R2 dan R3 secara bersama menjalankan routing OSPF dan RIP serta me-redistribution dari OSPF ke RIP maupun sebaliknya.
